Spurious "Couldn't resolve hostname"

Anyone else getting this? I've had it from one or two addresses,
for example:
http://www.natwest.com/global/customer-charter/g1/ideas-bank.ashx

gives me the error "Couldn't resolve hostname" yet the host name appears
to be OK. What's more if I delete the last element NetSurf does resolve
the host name and gives me an expected 404 error.
